CHIMNEY-SUPPORT FOR TELEGRAPH-WlRES.

SPECIPICATIONZorming part of Letters Patent lv'o. 340,520,:iated April 20, 1886.

Serial No. 187,195. (No model.)

To aZZ whom it 72mg concern.-

Be it known that I, ALBERT Form, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful improvement in Chimney-Supports for Telegraphires, of which the following is a specification, reference being had to the annexed drawings, forming a part thereof.

The object of my invention is to provide an attachment to chimneys for supporting wires for conducting electrical currents for telegraphic, telephonic, electriclight, and other purposes.

My invention consists of a frame clamped to the chimney-top and supporting a short telegraph-pole suitably braced, the frame and the pole being provided with insulators for sup porting the electrical conductors in the usual way.

in the drawing, which is a perspective view of a chimneyiop with my improvement applied, A is a frame, formed of side bars, a a, clamped against opposite sides of the chimney B by bolts 1), which pass through the bars a. a near the narrower sides of the chimney. A bar, C, extends across the dividing-wall of the chimney, and is secured to the upper side of the frame A by bolts 0, passing through the cross-bar O and through the bars a of the frame A.

In the center of the crossbar O is secured a short telegraph pole, D, which is provided with the cross-arms (Z in the usual way. The

' pole D, besides being secured in a mortise in the crossbar O, is further secured by the bracerods e, which are attached to the poleD a short distance above the lower end thereof, and are secured to the ends of the bars a, which project beyond the narrower sides of the chimney.

The bars a are preferably clamped just below the cornice of the chimney, and to admit of placing the bar 0 in its position on the top of the frame A some of the bricks of the cornice of the chimney and of the dividing-wall are removed. The bars a are provided with short standardsf, having on, their upper ends insulators g, which are supported a short distance above the chimney, to admit of extending the wires supported by the insulators over the top of the chimney. The crossbars dare provided with the usual insulators, g.

My improved support for telegraph-wires receives the wires in the usual way, and to form a connection between the telegraph'wires and the instruments in the building to which the chimney B belongs the wires are extended down through the chimney into the building.

My improved support maybe applied to or removed from the chimney without injury to it, and it forms an eiiicient support for the wires above the tops of the building, where they are least likely to be injured by firemen.

By the employment of myimproved system street-poles may be dispensed with, while the good qualities of the aerial system may bepreserved. It is beneficial rather than injurious to the chimney, as it clamps theupper courses of brick together and holds them in their place in the chimney-top. It also avoids the disfigurement and injury which commonly result from attaching wire-supports to different parts of the roof or walls of a building.

Havingthus described my invention,wl1at I claim as new, and desire to secure by Letters Patent, is-= 1. A chimney-support for telegraph-wires, formed of a frame adapted to be clamped to the chimney-top, and provided with a pole and suitable insulators for supporting the wires above the chimney in position to be led down the interior of the chimney, as and for the purpose specified.

2. The combination of the side bars, a, bolts b,extending through the side bars and clamp ing them to the chimney-top, the cross-bar O, the telegraph-pole D, braces e, and insulators 9, supported by the pole and the bars a, substantially as shown and described.
